The investigators will be assessing the efficacy of a Model Based Iterative Reconstruction algorithm (MBIR) as a noise reduction tool in computed tomographic (CT) examinations for Crohn's Disease. MBIR is computer adapted mathematical calculation technique that generates CT images with less picture degradation (noise) than traditional computer reconstruction techniques such as FBP (Filtered Back Projection) and ASIR (Adaptive Statistical Iterative Reconstruction), for enteric Crohn's Disease findings.
